IMPRGVEMENT 5N ELECTRQ-MAGNETIC MOTORS.

Specification forming part of Letters Patent No. 131.377, datedSeptember 17, 1872; antcdated September 9, 1872.

To all to whom it may concern:

Beit known that I, ADOLPH SOHREIBER, of Brooklyn, E. D., in the countyof Kings and State of N ew York, have invented a new and ImprovedElectro-Magnetic Motor; and I do hereby declare the following to be afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same,reference beinghad to theaccompanying drawing formin g part of this specification, in whichdrawing- Figure l represents a side view of this invention. Fig. 2 is aplan or top view of the same. Fig. 3 is an end view of one set ofelectromagnets, showing their connection with each other. Fig. 4 is atransverse section of my apparatus showing the commutator.

Similar letters indicate corresponding parts. y This invention consistsin the combination of two sets of electro-magnets with each other andwith a commutator, one set ofelectromagnets being mounted on astationary pin opposite the other set, which is mounted on a revolvingshaft, on which is also secured lthe commutator in such a manner thatwhen currents of electricity are passed through both sets ofelectro-magnets, and the movable electro-magnets are so placed as tobring their poles opposite to the homonymous poles of the stationaryelectro-magnets, then, by the repulsion of the homonymous poles and bythe attraction of the heteronymous poles, the movable electro-magnetsare caused to revolve, and as the polarity of these electro-magnets isconstantly changed by the commutator, a continuous revolving motion isimparted to the shaft carrying the movable electromagnets. By connectingboth sets of electro-magnets to one and the same battery the power ofthemotor is materially increased.

In the drawing the letter A designates a pin, which is secured in astandard, B, rising from a table, C, and on this pin is firmlysecured adisk, D, on which are fastened a series of electro-magnets at equaldistances apart. (See Fig. 3.) In the drawing I have shown eightelectro-magnets, which I have designated by the letters E1 EZES. E8, butthe number of the electro-magnets may be greater or smaller, accordingto the diameter of the disk D and to the power desired. One end of thehelix of the electro-magnet E1 connects by a wire, l0,

with one-say the positivepole of a galvanicbattery, F, while the otherend of said helix connects with the helix of the electro-magnet E2,which connects with the helix of the next electro-magnet E3, and soon,while the end of the helix ofthe last electro-magnet E8 connects by awire, ll, with the negative pole of the battery. By these means thepoles of the electromagnets El, E3, E5, and E7 will be north, and thoseof the electro-magnets E2, E4, E6, and E8 will be south, as indicated bythe letters N and S, marked, respectively, on said electromagnets inFig. l. The end of the pin A is sharp pointed to catch in a hole boredin the center of a shaft, H, which is mounted in a standard, H', risingfrom the table C, so that it revolves freely in its bearings. On thisshaft is mounted a disk, I, carrying a series of electromagnets J1J2J3 J8, which correspondin number and position to the electro-magnets E1 .E,and the helices of all of which are connected together, with theexception of those of the electro-magnets J1 and J 8, which areconnected at one of their ends each to one ofthe sections of thecommutator K. This commutator consists of a disk of wood or othernon-conducting` material, surrounded by a strip of metal, which isdivided in anumber ofsections, falaz a3. a8, corresponding to theelectro-magnets J1. .J B, the sections al, a3, a5, and a7 being inmetallic contact, (see Fig. 4,) and also connected to the en d of thehelix J1, while the sections, a2, a4, a, and a8 are also in metalliccontact with each other and connected with the helix J 8. On theeircumference of the commutator K bear two springs L1 L2, the spring L1being connected by a wire, 13, with the positive, and the spring L2 by awire, 14E, with the negative pole of the battery. If the shaft Hoccupies the position shown in the drawing the poles of theelectromagnets J1, J 3, J5, and J 7 are north, and those of theelectro-magnets J 2, J 4,' J 6, and J 8 are south, and the hornonymouspoles of the electromagnets Elr E8 repel those of the electromagnetsJ1.. .J8, causing the shaft H to revolve. As soon as the commutatorspring L1 passes on the segment a4 and the spring L2 on the segment c5,the current through the electromagnets J1 .J 8is reversed, and bythetime the electro-magnets J 2, J 4, J @and J 8have advanced to thepositions previously occupied by the electro-magnets J1, J3, J5, and J7,the poles"A have changed, those of the former to north and those of thelatter to south. The motion of the shaft H, therefore, will continueWithout interruption. The pin A, which supports the electro-magnets El..E, cany be turned in its standard, and it will readily be seen that, byturning the same so that the electro-magnets E2, E4, E6, and E8 willcome in the posiytion previously occupied by the electro-magnetsE1,E3,E5, and Erl the motion of the shaft H will be stopped, for in thiscase the south poles of the electro-magnets El. .E8 would stand oppositethe north poles of the electro-magnets J1 J 8, and vice versa; but, byturningthe pin A to an intermediate position, the motion of the shaft HWill only be retarded Without being stopped entirely, and I am thusenabled to regulate the speed of my machine in a very.

simple manner and with the greatest nicety. It Will be noticed that bothsets of electromagnets E1. .E8 and J1. .J8 are connected to the poles ofone andthe same battery, for I have found that, by using one and thesame battery for both sets of electro-magnets, the power of my machineis materially increased. This phenomenon I am unable to explain, but

the fact is undoubted, and l expect, by further experiments, to detector explain the cause producing this effect.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of two sets of electromagnets with each other andwith` a commutator, one set of electro-magnetsbeing mounted on astationary pin opposite the other set,

which is mounted on a revolving shaft, also` Witnesses W. HAUFF,.. E. F.KAsrENHUBER.
